It's a time-honored adage that anyone in Washington who wants a friend had better get a dog. But who knew that man's best friend would also be a boon to Greek rioters?

Amid the turmoil of the Greece financial crisis, photos and videos of street protests have turned up a kind of canine "Where's Waldo" figure: a mutt that may have some German shepherd genes, and clearly has a strong interest in civic disorder.

While one can't be certain that it's the same pooch at every protest — Athens is something of a magnet for street-savvy stray dogs — this mutt does sport a distinctive blue collar, which may indicate that, while he's a stray, he's also current on his shots.

By some accounts, the dog has been on the Athens protest scene ever since 2008 (though some say the 2008 pooch is a similar-looking dog named Kanellos who established himself as a fixture at demonstrations and died that year).

The current mutt has won a long string of blogtributes and a number of online nicknames, including "Rebel Dog," "Riot Dog" and "Protest Dog." He even has a Facebook page devoted to him (as "Riot-Dog"). Here's a sample of his protest outings (with apologies to Kanellos partisans if he's inadvertently included here).

The REBEL DOG blog is a work in progress. We will keep on adding more photos of this rebel dog. If you want to contribute to this series of photos please send your photo to revoltingdog@gmail.com (please, just photos of the specific dog) If you are a TWITTER user you can follow us @rebeldog_ath

Rebel Dog is just one of the new generation of political strays. You can find strays attending demostrations in many cities of Greece, such as Thessaloniki. All the dogs would like to be like Kanellos, free, happy and restless

A song for the dog, Kanelos / who bit me but I understand him / he consists in his point of view with passion / that I wrongly live my life

On a demostration about education cuts. Greece cannot afford money for education but must buy ships, planes, submarines and weaponry from our good - weapon manufacturing - allies, so that we have to borrow money from them and from the IMF in inconceivably high rates of interest.

interesting isn’t it?

Got milk?

The greek farmers infront of the parliament, spilled milk on the street. They protest over the highway robbery by the big dairy multinational companies who are buying the farmers’ milk for nothing and are selling it to the people at very high prices.

Rebel dog is on the side of the farmers. In the meanwhile he is testing the milk and finds it quite delicious

Today 3 people died because some criminaly idiot criminals set fire in a bank, here in Athens. This is not a revolutionary act, you fools, it’s murder.A huge demostration of people and the lives of three ruined so foolisly. The head of the Bank, as it seems, gave orders to the managers to keep employees working or else they would be fired. This bank’s branch was right in the middle of the demostration area and was not secured or had any fire-safety measures. As a result of all of the above three workers died from asphyxiation, before anyone can manage to save them.This is a very sad day for anyone with a consciense.
